1.   Absolute MSF address repeated in the header field of data blocks.
2.   The CD data mode is stored in the header of data tracks. This
     indicates that the block is part of a data pre-gap or post gap (nu=
ll),
     that this is a data block using the auxiliary field for L-EC symbo=
ls
     (ECC-CD data mode one), or that this is a data block using the
     auxiliary field for user data (CD data mode 2.)
3.   Table of Contents information is stored in the sub-channel of lead=
